SA4000 - NC - Performance issue with mapped network drives

We have some users that are experiencing performance issues with mapped network drives.
I was suspected a problem in the definition of the resource ports because when we use a role that open all servers/all ports, we don’t get the problem

This is the setup
DC
tcp://x.x.x.x:53,88,135,139,389,445,3268,1025
udp://x.x.x.x:53,135,139,389,445
